Q:

Bucking of column means

A) Lateral deflection B) Axial deflection
C) Torsional deflection D) None of the listed
 
Answer & Explanation Answer: D) None of the listed

Explanation: Buckling is characterised by lateral deflection but it is different from lateral deflection as there is sudden lateral deflection in buckling unlike lateral deflection where there is gradual deflection.

Q:

Small sheaves are preferred over large sheaves on what parameters?

A) Increasingly centrifugal force in large sheaves B) Higher cost of small sheaves
C) Preferring centrifugal force reduction even for more money D) None of the listed
 
Answer & Explanation Answer: A) Increasingly centrifugal force in large sheaves

Explanation: Larger sheaves have higher centrifugal forces and higher cost because more material is used in their construction.

It is observed acceleration in such cases is 1.2m/s².10mm diameter wire ropes with fibre core are used. The tensile designation of the wire is 1500.Number of rope wires is assumed to be 2. Number of rope wires is assumed to be 2. Calculate the weight of wire if weight of 50m wire is 18kg. Calculate the force due to acceleration.

A) 1000N B) 309.144N
C) 504.225N D) 102.225N
 
Answer & Explanation Answer: B) 309.144N

Explanation: Mass of material raised by each wire rope= 2450/9.81 = 249.7kg. Mass of each wire rope= 77.7/9.81 =7.92kg. Force due to acceleration= [249.7+7.92] x 1.2.
